Commercial Unitary Air 

Conditioners and Heat Pumps

The U.S. Department of Energy (DOE or the Department) is required by 

the Energy Policy and Conservation Act and its amendments to consider 

national energy conservation standards for certain commercial unitary air 

conditioners and heat pumps.

The Department has gathered and analyzed data and information for the 

Advance Notice of Proposed Rulemaking (ANOPR) and its Technical 

Support Document (TSD), as part of the standards rulemaking process. 

To fulfill DOE's commitment to the July 1996 Process Rule (61 FR 36974) 

— to make information available to the public as soon as possible — the 

ANOPR document, the TSD, and the analysis tools for the ANOPR analysis 

are available below.

Energy Conservation Standard Rulemaking

● Notice of Availability: The Department of Energy announces the 

availability of the "Joint Stakeholders Comments on Standards for 

Commercial Package Air Conditioners and Heat Pumps" and an 

opportunity for public comment. Federal Register, February 15, 

2005, (PDF 59 KB)

The Department received comments from a group of nineteen significant 

stakeholders in response to the Advance Notice of Proposed Rulemaking 

for Commercial Unitary Air Conditioners and Heat Pumps. 69 FR 45460 

(July 29, 2004). In summary, the Joint Stakeholders recommend 

minimum energy efficiency ratios (EERs) and coefficients of performance 

(COPs) for certain commercial unitary air conditioners and heat pumps, 

both split and package systems, respectively, as follows:

Air-Cooled Products Efficiency Standards

>65,000 - <135,000 Btu/h 11.2/11.0 EER for Air Conditioners

11.0/10.8 EER for Heat Pumps

3.3 COP @ 47oF for Heat Pumps

>135,000 - <240,000 Btu/h 11.0/10.8 EER for Air Conditioners

10.6/10.4 EER for Heat Pumps

3.2 COP @ 47oF for Heat Pumps

NOTE: Where two EERs are listed, the first refers to systems with electric 

resistance heat or no heating, and the second refers to systems with all 

other heating-system types that are integrated into the unitary equipment.

Further, the Joint Stakeholders have asked DOE to adopt January 1, 

2010, as the effective date for compliance with the recommended

minimum efficiency standards. (PDF 251 KB)

To help DOE determine the appropriate next step in this rulemaking, DOE 

invites interested members of the public to submit any comments they 

may have on the Joint Stakeholders Comments, including the 

recommendation for expediting proceedings by adopting these 

recommended efficiency standards through a direct final rule.

Comments must be submitted to one of the addresses listed in the 

ADDRESSES section of the above Notice of Availability. The Department 

will accept written comments, data, and information regarding the Joint 

Stakeholders Comments until April 1, 2005.
